I have never had luck with any miniature rose I've purchased. As soon as I bring them home they begin to wilt and die. It didn't matter where I located them...in the house, on the patio, planted in the ground. Maybe I gave them to much water or not enough water. Or maybe I gave them to much sunlight or not enough sunlight.
Then a few months ago my sister brought me home a miniature red rose as a surprise! I really felt bad for it. I knew it's fate. But surprisingly, the little red rose is thriving! After the first bloom, I replanted it into a larger pot and put it on the patio. I am amazed at how well it's doing! It's about three or four times it's original size!
Today, as I was giving Little Red Rose (yes I named it...after all it's a survivor) a drink of water, I'm almost sure I heard it whisper..."see...I told you I wouldn't die on you" :)
